Moscow, Russia -- Construction workers in central Moscow have found 60 bone fragments of a skeleton while excavating.

The bones appeared to be old and belonged to a human skeleton. They were found 3 meters below the surface. A forensic investigation is taking place on the bones.

This is not the first time human remains were found at a Moscow construction site. In September, two bags filled will parts of a male corpse were found covered in concrete while renovating a building. The remains were found near a medical institute that studies the effects of chemical, physical, and biological factors on humans.

Last month, Moscow residents also found a human skull and two bones in the middle of the road after an excavator dug them up during construction work.
